This over-the-counter medication is applied topically. Research has indicated that approximately 50% of men who apply this medication consistently will experience some reduction in hair loss and possible re-growth of miniaturized hairs. The generic liquid formulation is a bit oily in nature. The brand name Rogaine® and the minoxidil generic foam increase the efficiency of delivering the active ingredients and it is much easier to use than the liquid as it dries quickly. The packaging instructs the user to apply the foam only to the crown and to do so twice a day. We have found that once daily is usually sufficient with the Rogaine®/minoxidil foam and should be applied to any areas that are thinning, not just the crown.
Minoxidil has been on the market for a long time and has no reported drug interactions. In rare cases minor skin irritation, heart palpitations, light headedness, and dizziness have been reported.
The active ingredient in Women’s Rogaine®, minoxidil, stimulates inactive follicles and has been proven in clinical trials to regrow hair. An article published in WebMD notes "Widely available in generic versions and under the brand name Rogaine®, minoxidil seems to be more effective for women suffering from diffuse androgenetic alopecia than it is for men."
The cost of Rogaine®/minoxidil varies from store to store, but we have found that Costco or Sam’s Club has the best pricing that typically runs about $40-$50 for a 4-pack that should last you up to 8 months. If you choose to use the liquid version, be aware that it will require you to patient apply the liquid twice a day on a consistent basis for it to be as effective as the foam version once a day, thereby negating any savings.
